+# OpenSCAD Atreides case design
+
+This directory contains a copy `atreides_3D.scad` of the original OpenSCAD script `atreides_case.scad` that generates Atreides case designs using a number of parameters and is rendered for 3D printing.
+
+The main parameters are:
+
+ - `angle` : one half of the angle between the left and the right groups of keys
+ - `n_rows`, `n_cols` : number of rows and columns to use
+ - `staggering_offsets` : column staggering offsets
+ - `cable_hole_width` : width of the hole for the USB cable
+ - `hand_separation` : distance between the left and the right groups of keys
+ - `screw_hole_radius` : radius of screw holes
+ - `use_notched_holes` (boolean) : whether notched Cherry MX switch holes are desired
+
+See comments in `atreides_case.scad` for details.
+
+To use, open this script in OpenSCAD, select **Compile and Render (CGAL)** in the **Design** menu, then select **Export as DXF...**.
+
+Use OpenSCAD to export .stl as necessary.
+
+Please note that the OpenSCAD version of the case is not a direct port of the canonical DXF; the screw placement is a little bit different, and the curve of the bottom edge sticks out a bit more.
